Four years ago, Alexis Lamoureux and his girlfriend Lotte van Riel were searching for a place to live when they heard about an abandoned 11th-century cave dwelling in France's Loire Valley, reports Vocativ.com. The so-called troglodyte home, which had been left decaying for the previous 25 years, was a network of unstable rooms that had no sewage, running water, or electricity — and was filled with trash. But! This meant the up-for-auction home was dirt-cheap — Alexis purchased it for €1 (approximately $1.34).

"I said, 'Well, you know I'm the only one, and you realize how much work needs to be done,'" Alexis told Vocativ.com. "I knew that if they didn't sell it, they would have been in charge of securing the place. They didn't want to spend that much money, and they just wanted to get rid of it." Alexis and Lotte spent three years saving money for the necessary renovations the cave required.

You can even stay in Alexis and Lotte's cave if you find yourself in France — the couple rents out a separate one-bedroom section of the cave on Airbnb for €50 a night. You can check out their Airbnb listing here, and see more photos of the space on the home's Facebook page.
